I am looking for a network security scanning software much like Retina (What I use now) to replace it. The company doesn't want to pay for it next year. So the verdict is .... no money, find something that does the same thing, and is free. I know there are some Unix tools out there, but I'm not much of a unix person so I need something that runs on windows and will pretty much the same thing Retina will. Any Ideas?
